Place the chocolate chips or cut chocolate pieces in a large bowl.
Pour the whipping cream into a saucepan, place at medium heat, and heat until small bubbles form around the edge of the cream.
Pour the warm heavy cream over the chocolate. Allow to sit for about 30 seconds. Whisk the ingredients for about 2 minutes, by hand. The end result is gorgeous, glossy ganache. You can save the extra ganache in an sealed container and refrigerate for up to five days.
For the drizzle effect, use a piping bag, or a large plastic storage bag, with a small hole cut at one corner.
